[0001] The present invention relates to the technical field of tensioners, and more specifically to a passive compensation type ship cable tensioner and mooring system based on cable state monitoring. Background Art

[0002] A ship cable tensioner is a device used to ensure that the ship cable maintains an appropriate tension during use. This device plays an important role in ship operations. The cable tensioner usually consists of a cable, a cable tensioning device, a cable adjuster, etc. The design of the tensioner enables the tension of the cable to be adjusted through a tensioning device, ensuring that the tension of the cable is always in a suitable state and will not deform or break due to external forces.

[0003] When adjacent two hulls are moored side by side or a hull is moored to a dock, since the marine cable is a non-rigid connection, when encountering large waves, the two hulls or the hulls of the mooring dock will have large amplitude motions due to the action of the waves, resulting in large relative motions between the two hulls, and causing damage to the mooring system or even damage to the hull.

[0008] As a further solution of the present invention: Oppositely arranged two first cross arms and two second cross arms are further fixed at the ends of the support.

The fixed cable bypasses the first wire roller and the second wire roller and is connected to the movable seat. Moreover, the position of the second wire roller can be changed by being driven by the first hydraulic cylinder, so that the pressure balance is maintained inside the control oil station and the cylinder body of the first hydraulic cylinder. Thus, when the external cable is loose, the movable end of the first hydraulic cylinder automatically extends under the action of pressure, driving the second wire roller to move away from the first wire roller in the assembly seat, and the fixed cable will be pulled. Furthermore, the end of the fixed cable away from the mooring bitt will generate a traction force on the winding and unwinding mechanism, so that the winding and unwinding mechanism pulls the external cable to tighten the external cable, achieving dynamic pressure balance, being able to adaptively adjust the tension according to the size of the wave and the lifting degree of the cable, and performing passive compensation according to the cable state monitoring, enabling the automatic control of the cable tension, effectively improving the connection safety; Secondly, in the present application, when performing the cable release operation, the second hydraulic cylinder can drive the braking mechanism and the winding and unwinding mechanism to move in sequence. The braking mechanism locks the position of the movable seat, so that the pressure balance state inside the control oil station and the cylinder body of the first hydraulic cylinder is locked. Then, the winding and unwinding mechanism can release a longer length of the external cable, avoiding the external cable and the rigging from easily rebounding rapidly due to the instant release of the taut state, bringing danger to the staff, and improving the work safety. At the same time, after the external cable is released, the cable tensioner can also maintain the normal adjustment and compensation work on the fixed cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element. It can be directly on another element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to another element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0029] Please refer to Figures 1 - 10 , in the embodiment of the present invention, a passive compensation type ship cable tensioner based on cable state monitoring includes a support 1, and further includes: a fixed cable 8, which is disposed on the support 1 and is connected to a winding mechanism installed on the support 1. One end of the fixed cable 8 is connected to a mooring bitt, and the other end is connected to a retracting and releasing mechanism disposed on the support 1. The winding mechanism is further connected to a passive compensation type driving mechanism disposed on the support 1. The passive compensation type driving mechanism can drive the winding mechanism to move so as to perform a tightening action on the fixed cable 8; an external cable 10, which is disposed on the support 1 and is connected to the retracting and releasing mechanism. The external cable 10 is used to connect an external rope. The retracting and releasing mechanism is further connected to two braking mechanisms disposed on the support 1. The braking mechanism can fix the state of the fixed cable 8 before the retracting and releasing mechanism releases the external cable 10.

[0030] Please refer to again Figure 4 , an assembly seat 25 is obliquely fixed on the support 1. The winding mechanism includes a first wire roller 4 and a second wire roller 5 disposed in the support 1 and the assembly seat 25. The fixed cable 8 is wound from the lower part of the first wire roller 4 to the upper part of the second wire roller 5, then wound out from the lower part of the first wire roller 4, and connected to the retracting and releasing mechanism. A through groove 2501 is provided on each side of the assembly seat 25. The rotating shaft of the second wire roller 5 passes through the through groove 2501 and is connected to the passive compensation type driving mechanism.

[0031] Furthermore, when the passive compensation drive mechanism moves, it can drive the second wire roller 5 to move along the length direction of the mounting seat 25 within the mounting seat 25. Correspondingly, the second wire roller 5 can move away from or closer to the first wire roller 4. When the second wire roller 5 moves away from the first wire roller 4, the fixed cable 8 wound between the first wire roller 4 and the second wire roller 5 will be pulled. Furthermore, one end of the fixed cable 8 away from the mooring bitt will generate a traction force on the winch mechanism, causing the winch mechanism to pull the external cable 10 and tighten the external cable 10, achieving the effect of buffering the relative movement between the two hulls caused by waves and improving the safety of the connection.

[0032] The passive compensation drive mechanism includes two first hydraulic cylinders 6 respectively installed on both sides of the support 1. The first hydraulic cylinders 6 are arranged along the length direction of the mounting seat 25, and the movable end of the first hydraulic cylinder 6 is connected to the rotating shaft of the second wire roller 5. The cylinder body of the first hydraulic cylinder 6 is connected with a control oil station arranged on the support 1, and the control oil station keeps pressure balance with the inside of the cylinder body of the first hydraulic cylinder 6, so that when the external cable 10 is slack, the movable end of the first hydraulic cylinder 6 can drive the second wire roller 5 to move away from the first wire roller 4 within the mounting seat 25.

[0033] Specifically, when two adjacent hulls are moored side by side, since the marine cable is a non-rigid connection, when encountering large waves, the two hulls will have a large wave difference due to the action of the waves, and then may cause a large relative movement between the two hulls, resulting in damage to the mooring system or even damage to the hull. At this time, in this application, since the control oil station keeps pressure balance with the inside of the cylinder body of the first hydraulic cylinder 6, when the external cable 10 is loose, the movable end of the first hydraulic cylinder 6 automatically extends under pressure, driving the second wire roller 5 to move away from the first wire roller 4 within the mounting seat 25, and the fixed cable 8 will be pulled. Furthermore, one end of the fixed cable 8 away from the mooring bitt will generate a traction force on the winch mechanism, causing the winch mechanism to pull the external cable 10 and tighten the external cable 10, achieving dynamic pressure balance, being able to adaptively adjust the tension according to the size of the waves and the degree of cable lifting, enabling automatic control of cable tension and effectively improving the safety of the connection.

[0034] It should be added that in specific implementation, the tensioner body is installed on the inner hull, the fixed cable 8 is connected to the onshore mooring bitt, and the external cable 10 is connected to another ship adjacent to the inner hull.

[0035] Please refer to again Figure 7 And Figure 8, two first cross arms 2 and two second cross arms 3 are fixedly arranged at the end of the support 1, and the retracting and releasing mechanism includes a movable seat 11 slidably arranged on the two first cross arms 2 and a third wire roller 9 rotatably installed on the movable seat 11. The external cable 10 is wound around the third wire roller 9, the fixed cable 8 is connected to the movable seat 11, the movable seat 11 cooperates with the braking mechanism, and the rotating shaft of the third wire roller 9 is connected to a power assembly installed on the two second cross arms 3.

[0036] When it is necessary to release the connection state between the two hulls (i.e., release the cable), the power assembly works, which will first drive the braking mechanism to move. The braking mechanism locks the position of the movable seat 11. Thus, the state of the fixed cable 8 is maintained, and the control oil station and the inside of the cylinder body of the first hydraulic cylinder 6 are locked in a pressure balance state. Immediately afterwards, the power assembly will drive the third wire roller 9 to rotate. Then, the third wire roller 9 will release the external cable 10, making the external cable 10 slack, so as to facilitate the staff to remove the rigging and avoid the inconvenience of removing the rigging due to the tight state of the external cable 10. Further, when the third wire roller 9 is directly driven to rotate without the position of the movable seat 11 being locked, in order to achieve pressure balance between the control oil station and the inside of the cylinder body of the first hydraulic cylinder 6, the external cable 10 will be tightened again, making it difficult to obtain an effective slack for the external cable 10. When the external cable 10 is too tight, when removing the rigging, the rigging is subjected to too much tension, which causes inconvenience to the removal work. And after the removal, the external cable 10 and the rigging are prone to quickly rebound due to the sudden release of the tightened state, which is likely to pose a danger to the staff. In view of this, the present application is provided with a braking mechanism, which first brakes the movable seat 11, and then the third wire roller 9 releases the external cable 10, making the connection end of the rigging slack, thus providing convenience for the rigging removal work and also improving the work safety. In addition, due to the existence of the braking mechanism, after the external cable 10 is removed, the movable seat 11 and the support 1 are fixed, so that the first hydraulic cylinder 6 can still adjust and maintain the state of the fixed cable 8 to ensure the mooring stability of the fixed cable 8.

[0037] Please refer to again Figure 9 With Figure 10, the power assembly includes a boosting structure installed between the two second cross arms 3 and a sliding and engaging structure connected to the boosting structure. The boosting structure can drive the sliding and engaging structure to move along the length direction of the second cross arm 3 and prompt the third wire roller 9 to rotate. The sliding and engaging structure includes a transmission shaft 14 rotatably installed between the two second cross arms 3 and a follower tube 15 rotatably installed on the movable seat 11 and slidably engaged with the transmission shaft 14. The follower tube 15 is connected to the rotating shaft of the third wire roller 9 through a bevel gear set 13. Two protrusion parts 1401 are formed on the outer wall of the transmission shaft 14, and two grooves 1501 adapted to the protrusion parts 1401 are provided on the inner wall of the follower tube 15, and the transmission shaft 14 is connected to the boosting structure.

[0038] Specifically, the bevel gear set 13 includes a first bevel gear fixedly installed on the follower tube 15 and a second bevel gear fixedly installed coaxially with the third wire roller 9, and the second bevel gear meshes with the first bevel gear.

[0039] During the hull mooring process, when the external cable 10 is loose, as the movable end of the first hydraulic cylinder 6 automatically extends under pressure, the fixed cable 8 will pull and tighten the external cable 10 through the movable seat 11. Correspondingly, the movable seat 11 drives the follower tube 15 to slide on the transmission shaft 14. Therefore, the position of the third wire roller 9 changes. The settings of the protrusion part 1401 and the groove 1501 can ensure that the subsequent boosting mechanism can smoothly drive the third wire roller 9 to rotate through the transmission shaft 14 and the follower tube 15 without affecting the position change of the third wire roller 9.

[0040] The boosting structure includes two second hydraulic cylinders 7 installed inside the support 1, a connecting frame 19 fixedly connecting the movable ends of the two second hydraulic cylinders 7, and a second driving sleeve 22 fixed on the connecting frame 19. The second driving sleeve 22 is slidably engaged with a winding and unwinding shaft 18 rotatably installed between the two second cross arms 3. The winding and unwinding shaft 18 is connected to the transmission shaft 14 through a first transmission belt 16. A groove body is provided on the outer wall of the winding and unwinding shaft 18, and a driving column adapted to the groove body is fixedly provided on the inner wall of the second driving sleeve 22. The driving column extends into the groove body and is slidably connected to the winding and unwinding shaft 18. The groove body includes a first sliding groove 1801 and a second sliding groove 1802 connected to each other. The first sliding groove 1801 is arranged along the axial direction of the winding and unwinding shaft 18, and the second sliding groove 1802 is arranged in a spiral shape.

[0041] During operation, the second hydraulic cylinder 7 acts actively, pushing the connecting frame 19 to drive the second drive sleeve 22 to slide axially along the winding and unwinding shaft 18. Correspondingly, the driving posts on the inner wall of the second drive sleeve 22 move linearly along the axial direction of the winding and unwinding shaft 18. The driving posts first pass through the first chute 1801. During this process, the winding and unwinding shaft 18 does not rotate, and the braking mechanism locks the position of the movable seat 11. Subsequently, the driving posts pass through the second chute 1802 and are in sliding fit with the winding and unwinding shaft 18, prompting the winding and unwinding shaft 18 to rotate. Thus, the winding and unwinding shaft 18 drives the transmission shaft 14 to rotate through the first transmission belt 16. The transmission shaft 14 drives the follower tube 15 to rotate through the protrusion 1401 and the groove 1501. The follower tube 15 drives the third wire roller 9 to rotate through the bevel gear set 13, making the external cable 10 slack, facilitating the safe removal of the rope by the staff.

[0042] Please refer to again Figure 9 , the braking mechanism includes a braking shaft 20 rotatably mounted on the second cross arm 3 and a first drive sleeve 21 fixed to the connecting frame 19 and slidably sleeved with the braking shaft 20. A convex post 2101 is fixed on the first drive sleeve 21. A folded line groove adapted to the convex post 2101 is provided on the outer wall of the braking shaft 20. The convex post 2101 extends into the folded line groove and is slidably connected to the braking shaft 20. The braking shaft 20 is connected with a locking structure. The folded line groove includes a connected first groove section 2001 and a second groove section 2002. The first groove section 2001 is arranged in a spiral shape, and the second groove section 2002 is arranged along the axial direction of the braking shaft 20.

[0043] The locking structure includes a follower shaft 23 rotatably mounted on the second cross arm 3 and connected to the braking shaft 20 through a second transmission belt 17, and a plurality of braking rods 24 fixed on the follower shaft 23. The plurality of braking rods 24 are equidistantly distributed along the axial direction of the follower shaft 23. The braking rods 24 cooperate with the protruding blocks 12 fixed on the side of the movable seat 11. An inclined surface is formed on each side of the protruding block 12.

[0044] Specifically, when the second hydraulic cylinder 7 drives the connecting frame 19 to drive the second driving sleeve 22 to slide on the retracting and extending shaft 18, the first driving sleeve 21 slides on the braking shaft 20. When the driving post on the inner wall of the second driving sleeve 22 passes through the first chute 1801, the convex post 2101 slides with the braking shaft 20 through the first groove section 2001, causing the braking shaft 20 to rotate. Furthermore, the braking shaft 20 drives the follower shaft 23 to rotate through the second transmission belt 17, and multiple braking rods 24 swing downward. Then, two adjacent braking rods 24 respectively act on both sides of the protruding block 12. Since the position of the movable seat 11 on the first cross arm 2 is not fixed, when the braking rod 24 acts on the inclined surface on the side of the protruding block 12, it will cause a small displacement between the protruding block 12 and the movable seat 11 until the convex post 2101 enters the second groove section 2002, that is, after the rotation of the braking shaft 20 and the follower shaft 23 ends, two adjacent braking rods 24 respectively abut against the inclined surfaces on both sides of the protruding block 12, playing a role of limiting and locking the movable seat 11. The control oil station is locked in a state of pressure balance with the inside of the cylinder body of the first hydraulic cylinder 6. Subsequently, when the convex post 2101 moves along the second groove section 2002, the driving post on the inner wall of the second driving sleeve 22 enters the second chute 1802, and this driving post slides with the retracting and extending shaft 18, causing the retracting and extending shaft 18 to rotate, and the third wire roller 9 releases the external cable 10. Therefore, the external cable 10 can be released for a longer length, avoiding the external cable 10 and the rigging from easily rebounding rapidly due to the sudden release of the tension state, which may pose a danger to the staff and improving the work safety.

[0045] As another embodiment of the present invention, a mooring system is also proposed, including the cable state monitoring-based passive compensation type ship cable tensioner described above.
